Add a default featured image to the media settings page. This featured image will show up if no featured image is set. Simple as that.

FAQ

My chosen featured image doesn’t show, why isn’t it working?

This plugin can’t guarantee that it works. That depends on the themes. Still I want to know if it fails, so contact me

Which functions can I use to display the featured image?

The plugin uses the default WordPress functions the_post_thumbnail or get_the_post_thumbnail. has_post_thumbnail will always return true. get_post_thumbnail_id will return the ID set on the post or the DFI you set.

Can I exclude a page or give it a different image?

Yes you can by using the builtin dfi_thumbnail_id filter. It will give you the post id which you can use to check against.

Don’t use a featured image on page 23

function dfi_skip_page ( $dfi_id, $post_id ) {
  if ( $post_id == 23 ) {
    return 0; // invalid id
  }
  return $dfi_id; // the original featured image id
}
add_filter( 'dfi_thumbnail_id', 'dfi_skip_page', 10 , 2 );

Use a different image for some categories

The example below only works if the post has ‘animals’ as a category. Assigning just ‘cats’ won’t work
To do that just don’t nest the if

function dfi_category ( $dfi_id, $post_id ) {
  // all which have 'animals' as a category
  if ( has_category( 'animals', $post_id ) ) {

    //sub category
    if ( has_category( 'cats', $post_id ) ) {
      return 7; // cats img
    } else if has_category( 'dogs', $post_id ) {
      return 8; // dogs img
    }

    return 6; // default animals picture
  }
  return $dfi_id; // the original featured image id
}
add_filter( 'dfi_thumbnail_id', 'dfi_category', 10, 2 );

Different image for the post_type ‘wiki’

function dfi_posttype_book ( $dfi_id, $post_id ) {
  $post = get_post($post_id);
  if ( 'wiki' === $post->post_type ) {
    return 31; // the image id
  }
  return $dfi_id; // the original featured image id
}
add_filter( 'dfi_thumbnail_id', 'dfi_posttype_book', 10, 2 );
Can I change the HTML of the image returned?

yes you can with the filter dfi_thumbnail_html.

function dfi_add_class($html, $post_id, $default_thumbnail_id, $size, $attr) {
    // add a class to the existing class list
    $attr['class'] .= ' my-class';

    return wp_get_attachment_image( $default_thumbnail_id, $size, false, $attr );
}
add_filter( 'dfi_thumbnail_html', 'dfi_add_class', 10, 5 );

評価

Fantastic little plugin

Absolutely love this little plugin, saved me a massive headache with my theme and site options. <3
Just activate and set the default image and away you go. Fits nicely with many other plugins I have active also.

That didn’t worked for me sir, I have installed your plugin on my https://www.atarehman.com & I want my picture to show when I want to share it on social media. But the featured images shows from a post, but not from what I have set via this plugin.
